I'll take this as a chance for story time.

Our party of five found out that the cultists we were chasing had a hideout underneath the store of a perfume trader, with the trader himself probably being a member of the cult, too.
We enter the store, pretending to be just regular ol' customers, and quickly figure out what the next step was: One of the doors was leading down into the basement. Ofcourse the trader won't just let us wander downstairs, and we decide on distracting him with talk while we slipped past the door one at a time, and try intimidation if things go wrong.
Everything works out well and one of us even took the opportunity to buy flamable perfume with the plan of using it as an improvised molotov cocktail (The guy convinced the shopkeeper that burning perfume was part of his culture. He never got around to using it).
At the end we realized a little flaw: The only person left to sneak past the shopkeeper and into the basement was our Paladin, the stereotypical big guy in plate armour, so naturally the worst member in our party for sneaking around in a well-lit store without anyone distracing the shopkeeper.
For some reason we didn't think of sneaking back out to assist him and let our rogue do the tricky sneak part, and we had already forgotten our intimidation-plan after the long trading conversations we had with the shoppekeep.
So, the paladin tries to be creative. He points at one of the shelfes and yells "There's a rat!"
Rolls for bluff.
Fumbles.

Nobody believes him about the rat, but at the same time everyone in the store was now paying full attention to him. If that wasn't bad enough, everything went downhill from here on out:
Desperate now, our armoured champion of the gods knocks a bottle out of the shelves presenting the perfume bottles. Maybe he thought this would make the trader start picking up the glass of the broken bottle, but instead the guy gets really pissed. He yells at the paladin to leave the store.
"Make me."
Angry as **** the store owner picks up a small bottle from behind his counter and runs over to the paladin, with clear intentions of throwing it at him. The paladin decides to take this opportunity to charge him head on, and he manages to do just that, but not before the small bottle hits him in the face.
Apparently the bottle contained stuff with a really, really disgustingly strong stench, and it also burns in his eyes like tear gas, but at least the shopowner now lies on the floor, knocked out cold by his collision with a heavy, armoured and sweaty bundle of big muscles. By now all shoppers have fled the store.
The paladin tries to shrug the pain in his eyes off, but fumbles again, and instead ends up flayling his arms around while yelling in pain at the top of his lungs, while the rest of us watched from the basement entrance in sheer disbelieve. He knocks over several shelves and soon the room is filled with an obnoxious mix of gasses from all the broken bottles of perfume now littering the floor. The gas is enough to knock the armoured dumbass out, and it took us two attempts to drag his ass into safety (the first time around the brave soul that ventured into the gas chamber to retrieve him had to turn back while trying not to throw up), and it took us a long time to get him back on his feet. From here on out he wasn't allowed to be without one of the others to prevent him from spectacularly ******* up again, and thankfully nothing like that happened.

We later found out the shop blew up because one of the watchmen that came to investigate lit his pipe in the store.


tl;dr: Never leave a paladin alone during a sneaking mission, or he might recreate a miniature Auschwitz by accident.
